Can I take slight issue with your comparison of doctors and healthcare workers, flamingo?
I agree both jobs are essential.
But I think the reason they are paid differently has as much to do with supply and demand as one being traditionally male work and the other female work.
For example, doctors (male and female) require a minimum of 5 years training before they qualify and after that they have to do their junior/senior years in hospital etc. before they specialise.
Healthcare workers don't need to be nearly as highly qualified, if at all.
So the former is in relatively short supply, whereas the latter is abundantly available. In economic terms, that is why one attracts the substantially higher salary than the other.
Of course, if you go far enough back, women were often the community healers anyway.
Incidentally, as a former career person and now full-time mother, I would like to see the job I do - raising the next generation - regarded as the essential work it is.
What could be more important than ensuring the continuation of the species and bringing up children to be valuable members of our society and guardians of our future?? And yes, my family is going to have to tighten our collective belt, but it was something I wanted to do. DH offered to be SAHD, but I wanted to spend these early years with my child/ren.
